Simple interest=prt

Since the company spends 20$ on each doll and sells each for 30$ thats a 10$ profit.
If the company spends 400$ on promotion it would take 40 dolls since
400$ / 10$(amount of profit per doll) = 40
so to make the promotion back it would be 40 dolls but the question was to make PROFIT so it must be 41 dolls
Fiona and Pip win some money and share it in the ratio 6:1. Fiona gets £35 more than Pip. How much did they get altogether?
Let Pip get be x and fiona get be x+35
Ratio = 6:1
It would like this for solving n
